Where is the difference between single -mode light module and multi -mode light module

In fact, the single -mode optical module and the multi -mode light module not only use different types of fiber, but also are also very different at other levels. As shown below:

Transmission distance:

Single -mode optical modules are usually used for long -distance transmission. Single light modules with different optical fiber wavelengths are different. Single -mode optical module, the wavelength of 1310 nanometers is largely lost during transmission, the dispersion is small, the transmission distance is usually within 40 kilometers, and the single -mode optical module with a optical fiber wavelength of 1550 nanometers is small during transmission, but the dispersion is large The transmission distance is usually more than 40 kilometers, and the farthest can reach 40 kilometers. Multi -mode light modules are usually used for short -range transmission, and the transmission distance is usually between 300 and 500 meters.

Scope of application:

According to the above introduction, single -mode optical modules are usually used to transmit networks with long distance and fast transmission speed, such as urban domain networks, passive optical fiber networks, etc. However, multi -mode light modules are usually used to transmit networks with short transmission and low transmission rates, such as data center computer rooms and local area networks.

illumination:

Single -mode light molds are different from multi -module modules. The single -mode light module uses LED or laser, LD or LED multi -mode light modules.

power:

The power consumption of the single -mode light module is usually larger than the multi -module module, but the power consumption of the optical module mainly depends on the parameters, models and brands of the optical module. Therefore, different parameters, models and brands of single -mode light module power consumption.
